OPEN AIR SHELTER.

To all whom it may concern:

Be it known that I, HENRY JOHN Fox Ross, a subject of the King of England, residing at Chesham, Bucks, England, have invented certain new and useful Improvements in or Applicable to Open-Air Shelters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

lfly invention relates to rotary open air shelters for consumpti'ves or for other purposes where' open air Without draft is required for automatically protecting the patients from wind and weather, without curtailing theadmission of fresh air.

According to my invention 1 construct a house of shelter in a. circular or polygonal form, with a segmental movable screen suspended from braced arms-attached-to a casting mounted on a vertical pivot fixed to the center of a roof beam. The roof is constructed with a heavy timber across the center to which is firmly secured a shaft on which a pivot is formed at the top, and projecting above the center of the roof. A casting isprovided with a conical socket to fit the pivot at its upper end and a ball bearing encircling the shaft at the base allows the casting to revolve freely in a vertical posi- To one side of the casting is bolted a wind vane and also a. set of arms which eX- tend over the roof without touching it and have their ends forged to shape to bolt to a semi-circular wind screen, which covers half or more of the opening around the body. The screen is thus suspended from the rigid central bearing and turns with; the least wind pressure on the vane without the screen touching the wind pressure is heavy enough on the lower portion of the screen to force it into contact with the body I place a roller on a vertical spindle at the bottom of the screen so that when forced inward it bears on the circular edge of the covering board on the body; normally it does not touch.

In order to enable my invention to be fully understood I will describe the same with reference to the accompanying drawings in which similar parts.

Serial No. 869,959. r v r i elevation of the moving partsg Fig. 4; is an elevation of a modified form of shelter constructedaccording to my invention; 1 5 is a plan of same; Fig. 6 shows a construe: tional detail drawn to a largerscale.

afis the body of the shelter either circular 'or polygonal with walls about half the height of the whole; y w

a are doors, I) isia semicircular screen at tached to the arms. g, b is a continuation of the upper ring of screen frame, 0 is the roof fixed to the frame, d, dare posts-com nected by bars (Z at the top and bottom to form the frame supporting theroof.

e is an iron casting formed hollowup the middle to receive a pivot 70, which fits into a plate e -bolted to the casting e which is v provided with a ball bearing Ziat the lower end of the pivo-t shaft. To this casting isbolted the wind vane 'f and the arms 9 are stiffened by the braces h which are hooked through the cap e and bolted to the armsg'. A covering board we is 'fixed to the top of the walls andhas an, outer circular edge against which rollers a bear. v

a is a heavy timber forming the central roof support and is bolted to the frame. Iron. plates j, j are fixed onthe upper and underside holding the shaft in a central and rigid position. The casting e is carried by this shaft which has a pivot formed on the too to fit the recess in the top of the casting e and is kept true by the ball bearing Z fixed to the bottom of the casting e. The weight of the casting, the vane f, the arms 9 and the screen I) are carried by the pivot on the top of the shaft is and these parts revolve freely around the same. Fig. 4 shows an elevation and Fig. 5 a plan of a modification in design in which the mechanism or moving parts are the same, but the body of the shelter is open all around from floor to roof which is supported by fixed frame posts d, d and the screen Z) is extended vdown to the fioor and forms a complete circle, of'the screen frame I), I) under the ing left open about half-way around and as low as desired; a door is provided in the screen as shown at g Fig. 5.

Fig. 6 shows ajportion of the screen I) and a piece of the covering board m. n is a roller on the vertical spindle 0 which passes.

through the lower member of the screen frame I) and is secured thereto by the nut 29; it is shown in its normal position opposite Flg,

the upper portion vane bep the vane and clear of the circular edge of the cover board m. Should the Wind pressure be suificient'to force in the bottom of the screen the roller 11, bears on the circular edge of m and prevents the screen rubbing against the frame. If" the design shown in Fig. 4 is used the covering board m is secured to the floor to serve as a track for the roller n.

It will be seen from the drawings and description that shelters constructed on this principle provide protection for the patient from Wind and Weather automatically, by the action of the Wind itself, the screen changing its position With the change in the direction of the Wind. If desired the frame can be left entirely open down to the floor and a semi-circular screen made to reach the floor and revolve around it.

W hat I claim and desire to secure by Letters Patent of the United States of America is i 1. In an open air shelter the combination of a fixed body portion having openings at the sides, a Wind screen pivotally supported from the center ofthe roof of the structure and a vane so set and attached With respect to the screen that When operated upon by the Wind it causes the sheltering portion of said screen to be moved into such a position as to shelter the interior of the structure substantially as described.

2. In an open air shelter the combination of'a fixed bodyportion having openings at the sides, means for supporting a vertical pivot shaft at thecenter of the roof, a part Copies of this patent may be obtained for five cents each, by r Washington, D. 0.

adapted to rotate upon the said shaft, means in connection With the said part for carrying a screen and other means in connection With the said part for carrying a wind vane substantially as and for the purposes described.

3. In an open air shelter the combination of a fixed body portion having openings at the sides, means for supporting a vertical pivot shaft at the center of the roof, a part adapted to rotate upon the said shaft, means in connection with the said part for carrying a screen, other means in connection with the said part for carrying a Wind vane and a roller in connection With the lower portion of the screen adapted to bear against the circular edge of a suitable part in connection With the body portion substantially as and for the purposes set forth.

4. In an open air shelter the combination of a substantially circular body portion having openings at the sides, means for supporting a vertical pivot at the center of the roof, a. framework rotatable about said pivot, a screen with an open portion connected to the said framework and a Wind vane carried by the said framework and so set With respect to the screen as to cause the open portion there-- of to be automatically directed away from the Wind substantially as described.

In testimony whereof, I afiix my signature, in presence of two Witnesses.
